Bio
Dr. Daniel Clark is a medical sociologist. He conducts investigations of risk factors for adverse physical and cognitive function and designs and evaluates interventions to address those risk factors. Only 10 to 20 percent of health outcomes are attributable to what is traditionally defined as health care — therapies and treatments for conditions and diseases once they arise. Dr. Clark is focused on the other 80 plus percent of health outcomes, those due to what we are exposed to and those caused by what we do all day, commencing at birth.Dr. Clark is particularly interested in primary prevention in high-risk populations. His focus has been on lifestyle interventions — including weight management, nutrition, and physical activity — that have been evaluated and implemented in federally qualified health centers.

Dr. Clark evaluates how preventive health interventions can be applied to elderly, vulnerable populations. His primary research interests are in the identification and modification of risk factors for chronic disease and physical impairment among socioeconomically disadvantaged adults.
